In 10K yellow gold at 5/16", the O pendant is both simple and meaningful: a gold circle at the collarbone that carries its wearer's initial and whatever larger meaning she brings to circular forms. Olivia, Ophelia, Odette, Odessa, Octavia - O names are relatively rare, which gives the O initial a particularity: when a woman wears an O, there are fewer of them in the room. The 18-20" adjustable box chain in 10K gold with spring ring clasp. Made in Italy.
